a flashlight for the Moon and a foam ball for Earth
a photograph of the Moon
two different sized foam balls to represent Earth and the Moon and a light source to represent the Sun
glowing star stickers placed against a black background

Answer 1

The best option to model the Moon's phase changes would be two different sized foam balls to represent Earth and the Moon and a light source to represent the Sun. This option allows for a hands-on, interactive representation of the Moon's phases and how they change as it orbits around the Earth.
